Teaching Design on Quantity of Material Based on Micro-analysis and Model Construction
"Quantity of matter"is the core concept of high school chemistry,which is difficult to understand abstract content,most students can only use but can not understand its connotation.In order to help students better understand and master the content,this paper combines the con-cepts of microscopic analysis and model construction to teach"quantity of matter"and its related concepts.Through concrete teaching,the ab-stract content is concreted,and students are guided to analyze problems in microscopic models by analogy from a macroscopic perspective,help-ing students to build a thinking framework for learning chemistry,inspiring and cultivating students'model-building thinking.
